What SEMCO Technologies does
SEMCO Technologies is a France-based pure-play designer and manufacturer of electrostatic chucks (eChucks), the precision wafer-handling components used in semiconductor manufacturing processes including PVD, CVD, ion implantation, etching, inspection, and handling. Founded in 1986 in Montpellier and headquartered in Castries, the company has built more than three decades of dedicated expertise in capacitive electrostatic chuck technology, with R&D, design, and production fully integrated at its Montpellier facility operating under ISO 7 cleanroom conditions. Since joining the ECM Group in 2016, SEMCO has functioned as a focused single-product specialist, transferring its legacy thermal treatment equipment line into the group's furnace operations.
The company's core offering is a proprietary capacitive ESC capable of clamping standard, thin, and ultra-thin wafers across a temperature range of -150°C to +650°C, using Coulombic-based clamping compatible with Si, III-V, and non-conductive substrates, multi-zone embedded heating with integrated temperature measurement, BSG thermal modeling tools, and custom-pattern wafer contact surfaces. Revenue is generated primarily through direct B2B sales of custom-engineered eChucks to leading semiconductor OEMs, fabs, foundries, and laboratories worldwide, supplemented by design collaboration, refurbishment, and after-sales services, alongside the affiliated Flowlink gas-components platform. Pricing is quote-based given the custom nature of each unit, and distribution is delivered through ECM Group's infrastructure of 10 international representatives and 3 service centers.
SEMCO completed its IPO on Euronext Growth Paris in 2025 with a total offering of €46.2 million and reported FY2025 revenue of €34.7 million (up 31.5% YoY), net income of €10.1 million, and an EBIT margin of 40.7%. The company commissioned an automated production line in December 2025 that doubled capacity to 4,000 eChucks per year, and has announced an additional €5M CAPEX-funded facility expansion at Montpellier to support a stated 2028 revenue target of over €55 million. SEMCO serves 17 active customers in the global semiconductor equipment supply chain and competes in the broader rapid thermal processing market alongside larger players including Applied Materials, Mattson Technology, and Axcelis Technologies.
